PQV (Product Quantity Variation)
PQV (Product Quantity Variation) is an inbound shipment defect: the units received at a fulfilment centre do not match the quantity declared in the shipping plan. The shipment arrives short or long against what was said to be on the way.
What is PQV?
PQV (Product Quantity Variation) is an inbound shipment defect: the units received at a fulfilment centre do not match the quantity declared in the shipping plan. The shipment arrives short or long against what was said to be on the way.
It is one of the defect types behind inbound performance metrics and chargebacks, and it is expensive out of proportion to its size. A twenty-unit discrepancy in a five-hundred-unit shipment looks trivial; the investigation it triggers, the inventory that stays in limbo while it is reconciled, and the effect on the seller’s inbound standing are not.
Why mismatches are more costly than they look
The inventory side is the immediate problem. Until the count is agreed, the affected units are not properly available — so demand arrives at a listing that cannot serve it, while the stock physically sits in the building. Working capital is locked in a reconciliation queue rather than replenishing a listing.
The compliance side compounds it. Variations accumulate as inbound defects, and repeated defects put shipment-creation privileges and inbound capacity at risk. As ever, fees are the warning and access is the real stake — an account whose freight cannot be counted reliably loses the flexibility to move stock when it needs to.
Preventing variations at the source
Variations almost always originate before the freight leaves: a factory miscount, an unrecorded partial pallet, a box count that was never physically verified. Which is why counting discipline beats reconciliation. Verify the outbound count against the packing list, match the packing list to the plan, and do it at the point of dispatch rather than trusting a document produced upstream.
Where third parties handle the freight, write the check into the process — a secondary weight or count verification before dispatch is cheap and catches exactly this class of error. Measuring internally helps too: % DV = |units received − units shipped| ÷ units shipped, tracked per shipment, so the causes surface before the defects do.
In practice
A brand submits a shipping plan for 500 units and its domestic third-party warehouse runs a weight check before the pallets leave. The centre scans exactly 500, the inventory ledger updates cleanly, stock becomes available for immediate purchase, and the inbound performance record stays unblemished — the discrepancy never happened because it was caught at dispatch.
How Harpy Media helps
Inbound accuracy is part of our supply chain controls: outbound counts verified before dispatch, third-party checks specified, and discrepancy patterns traced back to the counting process that produces them.
PQV FAQ
What is product quantity variation?
An inbound defect where the quantity received at a fulfilment centre differs from the quantity declared in the shipping plan — a shortage or overage detected at receiving.
What happens when a shipment quantity does not match?
The discrepancy triggers an investigation and an inbound defect on your record. Affected units are not properly available until reconciled, and repeated defects can affect your inbound privileges and capacity.
How do I prevent quantity variations?
Count and verify before freight leaves: outbound quantities checked against the packing list, third-party warehouses asked to run a secondary check, and suppliers held to the same discipline. Most variances originate at packing, not in transit.
